1 Microsoft ® Official Course Module 9 Implementing Local Storage

2 Module Overview Overview of Storage Managing Disks and Volumes Implementing Storage Spaces

3 Lesson 1: Overview of Storage Disk Types and Performance What Is Direct Attached Storage? What Is Network Attached Storage? What Is a SAN? What Is RAID? RAID Levels

4 Disk Types and Performance EIDE SCSI SATA SAS Cost Performance Slow Slow ~ 150 IOPS ~210 IOPS Fast: 1.5mio IPOS SSD As performance increases, so does cost

5 What Is Direct Attached Storage? Advantages:Disadvantages: Easy to configure Inexpensive solution Isolated because it attaches only to a single server Slower DAS disks are physically attached to the server Server with attached disks

6 What Is Network Attached Storage? Advantages: Relatively inexpensive Easy to configure Disadvantages: Slower access times Not an enterprise solution NAS is storage that is attached to a dedicated storage device and accessed through network shares NAS offers centralized storage at an affordable price File Server Local Area Network (Ethernet) File-level access (CIFS, NFS) NAS Device

7 What Is a SAN? Advantages: Fastest access times Easily expandable Centralized storage High level of redundancy Disadvantages: More expensive Requires specialized skills SANs offers higher availability with the most flexibility Servers Storage Devices Switches SANs can be implemented using Fibre Channel or iSCSI

8 What Is RAID? RAID combines multiple disks into a single logical unit to provide fault tolerance and performance RAID provides fault tolerance by using: Disk mirroring Parity information RAID can provide performance benefits by spreading disk I/O across multiple disks RAID can be configured using several different levels RAID should not replace server backups

9 RAID Levels Each pair of disks is mirrored, then the mirrored disks are striped RAID 1+0 Block level striped set with parity distributed across all disks RAID 6 Block level striped set with parity distributed across all disks RAID 5 Mirrored drives RAID 1 Striped set without parity or mirroring RAID 0

10 Lesson 2: Managing Disks and Volumes Selecting a Partition Table Format Selecting a Disk Type Selecting a File System What Is ReFS? What Are Mount Points and Links? Demonstration: Creating Mount Points and Links Extending and Shrinking Volumes

11 Selecting a Partition Table Format GPT GPT is the successor of MBR partition table format Supports a maximum of 128 partitions per drive Can partition a disk up to 18 EB MBR Standard Partition table format since early 1980s Supports a maximum of 4 primary partitions per drive Can partition a disk up to 2 TB Use MBR for disks smaller than 2 TB Use GPT for disks larger than 2 TB

12 Selecting a Disk Type Basic disks are: Disks initialized for basic storage The default storage for Windows operating system Dynamic disks can: Be modified without restarting Windows Provide several options for configuring volumes Disk volume requirements include: A system volume for hardware-specific files that are required to start the server A boot volume for the Windows operating system files

13 Selecting a File System FAT provides: Basic file system Partition size limitations FAT32 to enable larger disks exFAT developed for flash drives NTFS provides: Metadata Auditing and journaling Security (ACLs and encryption) ReFS provides: Backward compatibility support for NTFS Enhanced data verification and error correction Support for larger files, directories, volumes, etc. When selecting a file system, consider the differences between FAT, NTFS, and ReFS

14 What Is ReFS? ReFS is a new file system that is built in to Windows Server Advantages include: Metadata integrity with checksums Integrity streams with user data integrity Allocation on write transactional model Large volume, file, and directory sizes (2^78 bytes with 16-KB cluster size) Storage pooling and virtualization Data striping for performance and redundancy Disk scrubbing for protection against latent disk errors Resiliency to corruptions with recovery Shared storage pools across machines

15 What Are Mount Points and Links? A mount point is a reference to a location on a disk that enables Windows operating system access to disk resources Use volume mount points: To mount volumes or disks as folders instead of using drive letters When you do not have drive letters available for creating new volumes To add disk space without changing the folder structure A link file contains a reference to another file or directory Link options: Symbolic file link (or, soft link) Symbolic directory link (or, directory junctions)

16 Demonstration: Creating Mount Points and Links In this demonstration, you will see how to: Create a mount point Create a directory junction for a folder Create a hard link for a file

18 Extending and Shrinking Volumes When you want to resize a disk, consider the following: You can extend or shrink NTFS volumes ReFS volumes can only be extended FAT/FAT32/exFAT cannot be resized You can shrink a volume only up to immovable files Bad clusters on a disk will prevent you from shrinking a volume You can resize NTFS volumes from the Windows operating system, beginning with Windows Vista and Windows Server 2008

19 Lesson 3: Implementing Storage Spaces What Is the Storage Spaces Feature? Virtual Disk Configuration Options Advanced Management Options for Storage Spaces Demonstration: Configuring Storage Spaces

20 What Is the Storage Spaces Feature? To create a virtual disk, you need the following: One or more physical disks Storage pool that includes the disks Virtual drives that are created with disks from the storage pool Disk drives that are based on virtual drives Use storage spaces to add physical disks of any type and size to a storage pool, and then create highly-available virtual disks from the storage pool Virtual drives are not virtual hard disks (VHDs); they should be considered a drive in Disk Manager Physical Disks Storage Pool Virtual Disk Disk Drive

21 Virtual Disk Configuration Options FeatureOptions Storage Layout Simple Two-way or three-way mirror Parity Disk sector size 512 or 512e Drive allocation Automatic Hot Spare Provisioning schemes Thin vs. fixed provisioning

22 Advanced Management Options for Storage Spaces Basic Management for Storage Spaces is available in Server Manager For disk failure: Do not use chkdsk or scan disk Remove the drive and add a new one Advanced management requires Windows PowerShell Windows PowerShell cmdletDescription Get-StoragePoolList storage pools Repair-VirtualDiskRepair a virtual disk Get-PhysicalDisk | Where{$_.HealthStatus -ne Healthy} List unhealthy physical disks Reset-PhysicalDisk Remove a physical disk from a storage pool Get-VirtualDisk | Get-PhysicalDisk List physical disks used for a virtual disk

23 Demonstration: Configuring Storage Spaces In this demonstration, you will see how to: Create a storage pool Create a virtual disk and a volume

25 Lab: Implementing Local Storage Exercise 1: Installing and Configuring a New Disk Exercise 2: Resizing Volumes Exercise 3: Configuring a Redundant Storage Space Logon Information Virtual machines20410B-LON-DC B-LON-SVR1 User nameAdatum\Administrator PasswordPa$$w0rd Estimated Time: 30 minutes

26 Lab Scenario A. Datum Corporation is a global engineering and manufacturing company with a head office based in London, England. An IT office and a data center are located in London to support the London location and other locations. A. Datum has recently deployed a Windows Server 2012 infrastructure with Windows 8 clients. You have been working for A. Datum for several years as a desktop support specialist. In this role, you visited desktop computers to troubleshoot application and network problems. You have recently accepted a promotion to the server support team. One of your first assignments is configuring the infrastructure service for a new branch office. Your manager has asked to add disk space to a file server. After creating volumes, your manager has also asked you to resize those volumes based on updated information he has been given. Finally, you need to make data storage redundant by creating a three-way mirrored virtual disk.

27 Lab Review At a minimum, how many disks must you add to a storage pool to create a three-way mirrored virtual disk? You have a USB-attached disk, four SAS disks, and one SATA disk that are attached to a Windows Server 2012 server. You want to provide a single volume to your users that they can use for file storage. What would you use?
